Digital Fingerprint Viewer

See what your browser leaks to trackers

Websites don’t need cookies to follow you. They collect a “digital fingerprint” — screen size, fonts, graphics card, battery level, timezone, and dozens of other device signals. With trillions of possible configurations, your setup may be unique among billions of users.

Privacy model, browser support, and how to report issues — documented for engineers and power users.

Are these Chrome extensions free?

Yes. Every extension on this page is completely free — no subscriptions, in-app purchases, or premium tiers.

Do you collect or sell user data?

No. These extensions are built with a local-first mindset. Analysis and audio processing run in your browser — nothing is tracked, profiled, or sold.

Why do some extensions need broad site permissions?

Permissions map directly to function. Volume Master Pro needs site access to attach to each tab’s AudioContext. Digital Fingerprint Viewer reads browser APIs locally to show what trackers could harvest — nothing is transmitted to external servers.

Which browsers are supported?

All extensions are built for Chromium browsers — Google Chrome, Brave, Edge, and other Manifest V3–compatible browsers. Install via the Chrome Web Store links on each card.
